ABSTRACT: According to the nuclear
safety regulations, this paper discusses the mechanical analysis method for
piping system. Peps program has advantages of stress analysis and evaluation
for nuclear piping. First, this paper introduces the Peps software, and
discusses the process of stress analysis and evaluation for nuclear piping
using the general finite element software; Secondly, taking nuclear class 2/3
piping system as an example, it uses Peps4.0 program to calculate the piping
stress in variety of working conditions, such as weight, pressure, thermal
expansion, earthquake, time-history force, and etc. Finally, the paper
calculates the maximum stress and stress ratio according to the ASME.
